先看下效果：
使用步骤：
1.编辑html页面。
<ul id="dynamicCondition" style="display:none;">
<li field="DynamicCondition.id" title="id" edit="text" layVerify="number"></li>
<li field="DynamicCondition.logicDel" title="是否有效" ops="equal" edit="editorRadio" layVerify=""></li>
<li field="DynamicCondition.name" title="姓名" ops="equal,like,end" edit="text" layVerify=""></li>
<li field="DynamicCondition.sex" title="性别" edit="select" layVerify="number" templet="#dict-sex"></li>
<li field="DynamicCondition.birthday" title="生日" edit="date" layVerify=""></li>
<li field="DynamicCondition.phone" title="手机号码" edit="text" layVerify=""></li>
<li field="DynamicCondition.email" title="邮箱" edit="text" layVerify=""></li>
<li field="DynamicCondition.province" title="省份" ops="equal" edit="selectProvince" templet="#dict-province" layVerify="" allowDel="false"></li>
<li field="DynamicCondition.city" title="城市" ops="equal" edit="selectCity" templet="#dict-city" layVerify="" allowDel="false"></li>
<li field="DynamicCondition.goodsClassifyId" title="商品分类" ops="equal" edit="goodsClassifyTree" layVerify="" ></li>
<li field="goodsClassifyId" title="下拉树" ops="equal" edit="treeSelect" placeholder="下拉树插件" layVerify=""
url="xpl/demo/dynamicCondition/treeSelect"
></li>
</ul>主要看最后一个li标签配置edit="treeSelect"与url="xpl/demo/dynamicCondition/treeSelect"
2.后台提供数据。即访问上面配置的url，返回指定格式数据。

3.引入相关组件。必须引入dynamicCondition组件与treeSelect组件才能正常使用。
因为集成了layui 第三方组件treeSelect(查看treeSelect组件说明)，所以需要引入该组件。例如：
layui.config({
base: '/static/layui-extend/' //设定扩展的Layui模块的所在目录，一般用于外部模块扩展
}).extend({
dynamicCondition: 'dynamicCondition/dynamicCondition',
treeSelect: 'treeSelect/treeSelect'
}).use(['table','form','dynamicCondition','treeSelect'], function(){
//业务代码....
})具体可以参考demo页面源码。
